STE-AND OR CORD WORKING- MECHANISM.

Original application filed July 31, 19-2-0, Serial No. 400,301. Divided and. this application filed March" 6,

T0 aZZ whom it may concern:

Be it known that we, Fnnonnro S. KOCH- nrmonrin-z and Sons N. SELVIG, a citizen of the United States, and a subject of the King of Norway, respectively, residing at River Forest, in the county of Cook and State of Illinois, and at Chicago, in the county of Cook and State of Illinois, respectively, have invented certain new and useful Improvements in Strand-or Cord Working Mechanism, of which the following isa full, clear, concise, and exact description.

This invention relates to improvements in strand or cord working mechanism, and more particularly to an improved means for reniovably supporting the spools employed in such mechanisms.

The object of the invention is to provide a spool supporting means of such character that the spool may be quickly applied and removed therefrom whereby the preparation of the machine for operation is facilitated and the activity of the machine increased.

This application is a division of our copending application, *Serial No. 400,301, filed July 81, 1920, and resulting in Patent No. 1,520,718, dated December 30, 1924:, which is a complete disclosure of a strand or cord working mechanism to which the improved means for supporting the spools herein disclosed is particularly adapted.

In the accompanying drawings which illustrate one embodiment of the invention,

Fig. 1 is a plan view, partly in section, of a mechanism for removably supporting a supply spool bearing made in accordance with the present invention;

Fig. 2 is a side view of the mechanism shown in Fig. 1, and

Fig. 8 is a detailed section taken on the line 33 of Fig. 2.

Referring now to the drawings in detail in which like reference numerals designate similar parts throughout the several views, a supply spool shaft 10 projects from the housing of the supply spool mechanism and terminates in a reduced end in a cone-shaped tip 11. Screw threaded on the shaft 10 just inside the tip is a co lar 12 equipped with a cone-shaped projection 13 which projects into anopening 14 in the supply spool and clamps it on the shaft 10. The cone-shaped tip 11 on the shaft 10 enters a similarly Serial No. 623,203.

16 is enlarged and provided with a cam groove 19 in which a pin 20 secured in the shaft 1'? rides when a handle 21 secured thereto is moved upward. The cam groove 10 is so shaped that the pin 20 in advancing in it slides the shaft 17 outward and due to a circular enlargement or shoulder 31 formed on the shaft which abuts the arm 16 the said arm is carried along therewith, thereby carrying the anti-friction bearing away from the cone-shaped tip 11 of the supply spool shaft 10 just enough to clear it. Centering and positioning lugs project from one side of the arm 16 and engage recesses 23 in the stationary sleeve 18. During the longitudinal movement of the arm 16 the lugs 22 are drawn from the recesses 23. A lug 24 on the handle 21 engages a shoulder 25 on the arm 16 at the end of the initial movement of the handle which movement longitudinally shifts the arm and thereafter a continued movement upward of the handle 21 carries the arm 16 upward enough to clear the outside diameter of the collar 12, as shown in dotted lines in 2.

A spring catch 26 carried in a recess in the arm is drawn from engagement with a recess 2'? in the bearing arm 16 at the beginning of its upw rd movement and at the end of the horizontal movement engages a second recess 28 in the bearing arm 16 which lOCKS the arm 16 and handle 21 together so 1. In a strand or cord working machine, a spool, means for supporting the spool, a movable support therefor,an actuating element for moving said support, and controlling means for said actuating element so designed that the support is moved longitudinally and laterally of the spool by said actuating element.

2. In a strand or cord working machine, a spool, a shaft therefor, a movable supporting bearing therefor, an actuating element for moving said bearing, and a guide for said actuating element so designed that the bearing is moved longitudinally and laterally of the spool by said actuating" element.

3. In a strand or cord working machine, a spool, a shaft therefor, a movable end bearing for said spool, supporting means for said bearing comprising a sleeve and a shaft, and means controlled by the rotation of the sleeve on the shaft to move said bear ing longitudinally and laterally away from the end of said spool.

4. In a strand or cord Working machine, a spool, means for supporting the spool, a movable support therefor. a rotatable element for moving said support and controlling means for said rotatable element so de signed that the support is moved longitudinally and laterally of the spool by a rotation of said rotatable element.

In a strand or cord working machine a spool, a shaft therefor, a movable support ing bearing therefor, an actuating elementfor moving said bearing, a guide for said actuating element so designed that the hearing is moved longitudinally and laterally of the spool by said actuating element, and means for latching said bearing to said actuating element.

6. In a strand or cord working; machine, a spool, a shaft therefor, a movable end bearing for said shaft, supporting means for said bearing comprising' a sleeve and a shaft, means cent-rolled by the rotation of the sleeve on the second mentioned shaft to move said bearing longitudinally and laterally avvay from the end of said spool, and means for latching the bearing to the second mentioned shaft.

In witness whereof, I hereunto subscribe my name this 23rd day of February A. I), 1923.
